The Institute of Aerospace Power Technology of China Fourth Aerospace Institute was established in 1962, and the largest solid rocket engine research and production base in China was built in Xi 'an. Aerospace power technology research institute has 16 design department (R&D center), research institute, factory and other production and living supporting units. The Institute of Aerospace Power Technology has successfully developed more than 70 kinds of solid rocket motors, and more than 40 of the more than 60 satellites successfully launched in China have used the solid motors developed by our institute. China Academy of Space Technology is the earliest high-tech unit engaged in satellite development in China, and it is also the most powerful main research base for satellites and spacecraft in China. In the past 38 years, the institute has successfully launched more than 70 satellites and 6 spacecraft. From June 5th to1October, 2003, the manned flight of Shenzhou 5 spacecraft developed by China Academy of Space Technology was a complete success. The Sixth Research Institute of Beijing-China Aerospace Science and Industry Group (also known as China Hexi Chemical Machinery Company) is the first solid rocket engine research and production base in China. 1965 1 month, renamed the Fourth Research Institute of the Seventh Ministry of Machinery Industry; In the same year, he moved northward to Hohhot, Inner Mongolia Autonomous Region; 1978 10 month, renamed as the Seventh Industrial Bureau of Inner Mongolia Autonomous Region; 1981May, renamed as the headquarters of the Fourth Research Institute of the Seventh Ministry of Machinery Industry of Inner Mongolia; 1In July, 1999, ten national defense science, technology and industry groups were established, and the Inner Mongolia base was changed to the Sixth Research Institute of China Aerospace Science and Industry Group. (Inner Mongolia) The Seventh Research Institute of China Aerospace Science and Technology Corporation (the Seventh Institute of Aerospace, Sichuan Aerospace Technology Research Institute) is a large-scale high-tech enterprise group based on aerospace and military-civilian integration. It is an important scientific research and production base of aerospace industry, and undertakes the production tasks of various national aerospace models. (Chengdu, Sichuan) The Eighth Research Institute of China Aerospace Science and Technology Corporation (referred to as the Eighth Institute) is a comprehensive research institute that undertakes a large number of aerospace product development tasks in China. It has undertaken various research and development tasks of different aerospace products, and formed three general institutes and corresponding assembly plants with application satellites, launch vehicles and tactical models as the core, as well as a number of professional and technical research institutes engaged in different professions. The Ninth Research Institute of China Aerospace Science and Industry Group is an aerospace high-tech research institute established on the basis of China Sanjiang Aerospace Group. The Ninth Institute mainly undertakes the national key aerospace high-tech products, and undertakes a series of pre-research, research and trial-production of related high-tech products. At the same time, as a well-known design and manufacturing unit of heavy off-road vehicles and chassis in China, it provides a series of products to meet the needs of downloading and heavy transportation under off-road conditions. The Ninth Hospital actively promotes the transfer of military technology to the civilian field, and the various civilian products developed and produced are marketed at home and abroad. The tertiary industry company controlled by Jiuyuan is involved in finance, real estate, communication and information services, logistics, trade, property management, tourism, new rural construction and other industries, and has formed an industrial chain development pattern that is led by real estate development and drives the development of related industries.
